(i didn't watch the video but) The method section in the wiki page says > 3. Stopping when reaching "Philosophy", or a page with no links, or when a loop occurs[4] So, philosophy is explicitly chosen by the method as the "positive" occurrence vs its absence. If this is not the case, then wiki is doing a bad job explaining I think.
